2. Fuel description

All current plutonium fuels for RNRs are based on mixed oxide UO 2 -PuO 2 , with the exception of a few experimental elements whose potential development is discussed at the end of this article.

2.1 Constituents UO2-PuO2

PuO 2 powder comes from the irradiated fuel processing plant, where it is packaged in sealed cans, each containing around 3 kg of powder. It is fully characterized in physical, chemical and isotopic terms.

The UO 2 powders most commonly used are wet-processed from depleted uranium U 3 O...
